Asymmetric Unit(hide GO term definitions)
Chain A   (IMM9_ECOLX | P13479)
molecular function
    GO:0015643    toxic substance binding    Interacting selectively and non-covalently with a toxic substance, a poisonous substance that causes damage to biological systems.
biological process
    GO:0030153    bacteriocin immunity    A process that mediates resistance to a bacteriocin: any of a heterogeneous group of polypeptide antibiotics that are secreted by certain bacterial strains and are able to kill cells of other susceptible (frequently related) strains after adsorption at specific receptors on the cell surface. They include the colicins, and their mechanisms of action vary.

Chain B   (CEA9_ECOLX | P09883)
molecular function
    GO:0004519    endonuclease activity    Catalysis of the hydrolysis of ester linkages within nucleic acids by creating internal breaks.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0004518    nuclease activity    Catalysis of the hydrolysis of ester linkages within nucleic acids.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
    GO:0019835    cytolysis    The rupture of cell membranes and the loss of cytoplasm.
    GO:0042742    defense response to bacterium    Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.
    GO:0090305    nucleic acid phosphodiester bond hydrolysis    The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis.
    GO:0009405    pathogenesis    The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
cellular component
    GO:0005727    extrachromosomal circular DNA    Circular DNA structures that are not part of a chromosome.
